It is not immediately clear what Pittsburgh will receive in exchange for McCutchen, a five-time All-Star outfielder who helped revitalize the Pirates franchise and led the club to three consecutive postseason appearances from 2013-15.

The Athletic was first Monday to report the deal, which would be the second major trade this offseason for both teams. The trade is pending the completion of a physical, according to reports.

McCutchen, 31, is entering the final year of his contract and had been the subject of widespread trade rumors for the past year.
